Leading Edge Technology
AM2 Niagara products feature a multiprocessor architecture, which guarantees that call volume is not affected by the number of operating channels or the nature of the tests that the user chooses to perform. Extensive use of high speed microprocessors and Digital Signal Processors (DSPs) make AM2 Niagara versatile, accurate and fast. All tone detectors are based on DSPs. Never needing calibration, AM2 Niagara systems will last well into the next generation of switching systems.
To maintain the maximum level of performance, functionality and flexibility, every AM2 Niagara is powered by a 32-bit RISC processor, controlled via user defined scripts and protocols and managed via FeatureCall, a Windows based graphical user interface. In addition, every line or channel in an AM2 Niagara is served by “local” DSPs to identify call progress tones, detect digits and to verify the voice path after a connection has been established. The combination of these capabilities allows the user of AM2 Niagara to create the complex call testing applications necessary to develop and test today’s communication systems and applications.
The Ameritec Commitment
Ameritec Corporation has been manufacturing Bulk Call Generators for testing switches with analog, PCM, ISDN and SS7 interfaces, as well as other telecommunications test equipment, for over fifteen years. Ameritec test equipment is used by major telecommunication equipment manufacturers,

Ameritec’s AM2 Niagara® family of products is comprised of fully self-contained portable test instruments designed to meet the rigid demands of today’s telephony applications developer in both laboratory and field applications. The AM2 Niagara, simply put, makes telephone calls -- and lots of them! Each AM2 Niagara unit allows interfacing to different line types. One model interfaces to Analog POTS lines, another to Analog P-Phones lines, others to T1, E1, PRI, BRI, and SS7. The AM2 Niagara allows users to develop a test environment with the ability to test highly complex call scenarios.
M o d e l s
Test configurations can, via Ameritec’s FeatureCall GUI, control up to 32 AM2 Niagara’s via an Ethernet® TCP/IP LAN.
Through the use of user defined call scripts and line protocols, users can tailor test scenarios to meet a wide range of testing requirements. Whether the testing demand is focused on development, production testing, quality assurance or regression testing, the AM2 Niagara family provides the flexibility to satisfy your testing needs.
The AM2 Niagara has the flexibility to serve a wide range of telephony testing requirements including both switch and network testing applications, in a captive lab or as a fully self-contained test tool. Whether your application calls for a single interface, or for multiple physical interfaces, the AM2 Niagara family
provides a configuration that will meet or exceed your needs.

Central Office or PBX Switches and Networks |
|
• |
Voice Over Packet (VoFR, VoIP) Systems |
|
• |
Intelligent Network (IN) applications |
|
• |
Voice Mail systems |

Each AM2 Niagara can simulate one to hundreds of telephony subscribers. The actions of each simulated subscriber are independently controlled through unique parameter fields defined in user programmed Call Scripts.
Scripts define calling patterns and can simulate practically any action a live caller can perform. Scripts also simulate multiple subscribers allowing testing of multiple-party calls such as conference calling.
Capabilities in Call Scripts include:
•Signaling: All interface specific signaling functions supported through Call Scripts and user programmable signaling protocols.
•Dialing: Multiple unlimited length dial strings, multiple dialing types, including in-band end-to-end signaling (e.g. DTMF digits for interactive applications).
•Digit decoding: Decode in-band DTMF or MF digits.
•Tone Send: Send pre-programmed single frequency tones.
•Tone Receive: Detect any single frequency tone.
•Path Verification: Comprehensive two-way verification of multiple party voice and data path connections via in-band sequences, BERT patterns, X.25 packet data, or packet drop detection (VoP).
•Voice Replay: Optional feature allowing replay of pre-recorded audio samples on demand.
•ADSI: Optional feature permits the testing of caller ID functionality.
• |
Delays: Event-to-Event delay measurements, round trip delays (VoP). |

Testing complex telephony applications requires you to develop many test cases. Limited programmability or learning a programming language used to be your choices - until ScriptMate! ScriptMate is a graphical tool that allows you to develop sophisticated test scripts by simply drawing the test sequence!
AM2 Niagara Call Generators offer you the ultimate in flexibility by providing powerful built-in test case scripting capabilities. This level of flexibility is what gives the AM2 Niagara its power. ScriptMate is a tool that unlocks this power with an intuitive, easy-to-use, graphical test script generation method.
ScriptMate is a companion program to FeatureCall and allows you to easily develop call test scripts by dragging, dropping and interconnecting simple icons to create a graphical Call Flow Diagram. With a single click of the mouse, the Call Flow Diagram is converted into a complete Script source file that can be loaded into your
AM2 Niagara using FeatureCall.
Create or modify your call flow diagram interactively
